I just downloaded lw and want to start using it. It is the LaunchAnywhere 4.5 Mac Edition. (I just got an iMac and am a latecomer to filesharing.) When lw is running, if I click away from it at all, to go to another app or to the Finder, it crashes with an "Error Type 2" and recommends I restart the computer.

Is this common; is there a fix; should I reinstall?

I'm a newbie and appreciate any help.
